I haven’t been experiencing any differences. Been using it for 4+ years.

Yeah, that would make sense!

I love the concept, but could anyone explain to me what the point of a physical robot hand is?

I understand that the children can’t yet read text so they need to see sign language, but what is the point of a physical hand and not a recording of a hand or a CGI hand?

A hand on the screen would:

• be silent
• need no specialized HW
• be cheaper

I can see the novelty of a physical robot hand, but if the point is to help as many children as possible, I don’t see why this is the better option.

Does anyone have more insight into this?

I think you could just store the signatures centrally for validity, no need to store the whole models.

If a task/chore can be done in 2 minutes or less, do it now.

Not sure if it is the best, but it is a simple piece of advice I follow religiously. I think the reason this makes sense is that the cognitive load of trying to remember to do it is higher than just doing it straight away.
